Implementation of Co-training Regressors (COREG) semi-supervised regression algorithm from Zhou and Li, 2005.
Hi nealjean,
thank you for the very interesting research paper and code example.
I want to rebuild the Coreg algorithm and apply it in my current university project.
But it seems, that the data_utils module for the function load_data can't be found anymore.
Is there a convenient alternative to it?
Regards,
Anton
I'm a phd student and I'm doing research into semi-supervised regression now. When searching about COREG, I find you have reproduced it in Github.
However, when I read function _compute_deltas below,
Lines 144 to 162 in 2ec44e2
y_u
in line 152 rather than y_u_hat
in line 153 to train h_temp
, and using self.U_y_pool
to add to training sets in line 218 of coreg.py. .Lines 215 to 221 in 2ec44e2
y_u
and self.U_y_pool
are parts of true labels of unlabeled training set self.y_unlabeled
or self.U_y
,Line 152 in 2ec44e2
Lines 241 to 242 in 2ec44e2
y_u_hat
which stores the estimated labels of unlabeled training set is mentioned only once in the file, I am doubtful whether you use the true labels of unlabeled training set in training process. In my opinion, unlabeled y shouldn't be used in training in semi-supervised learning task.A declarative, efficient, and flexible JavaScript library for building user interfaces.
